One night, meat was plentiful. A man named Potok had killed a cave bear after a fierce battle. Our bellies were full and grease hissed in the fire, and when we had eaten, Potok stood and told his tale: how he had lured the bear and crept upon it, how his spear went deep, and then he leapt upon the bear with his flint knife. The bear’s fangs hung, fresh and bloody, from a thong about his neck.
